ADDITIONS TO THE CATALOG OF OHIO VASCULAR 



PLANTS FOR 1918.* 



John H. Schaffner. 



During the past year a number of botanists have made 

 interesting collections of native and introduced plants, speci- 

 mens of which have been placed in the State Herbarium. 

 Strange plants continue to appear in Ohio from year to year 

 and some of these will, without doubt, finally become a part 

 of our normal flora. There are probably also quite a number 

 of uncommon native plants which have not yet been reported 

 and much work remains to be done before the geographical 

 distribution of our indigenous species will become fairly well 

 known. The natural geographic boundaries marked out by 

 certain species will be of great value in delimiting the natural 

 agricultural and horticultural areas of the state; so that, while 

 individual observations may not in themselves be of great 

 value, many observations over the entire state will eventually 

 give us knowledge of great importance. It is hoped, therefore, 

 that the botanists of the state will continue work along this 

 line as in the past and send specimens of the unusual species 

 to the State Herbarium as well as to herbaria that may exist 

 in local institutions. 



The Catalog of Ohio Vascular Plants was issued by the Ohio 

 Biological Survey in March 1914, and during the five years 

 since then additions and corrections have been published an- 

 nually. Including the present list, 47 new species and varieties 

 have been added, and authentic specimens have been secured 

 of many plants on the original list which were not represented 

 in the herbarium. It is especially desired that every species 

 in the catalog be represented by at least one authentic specimen.
